I'm going to be in Las Vegas from Feb 22 until Feb 27 to visit the IBM Pulse conference. This is a pretty good time to meet and talk about BVQ business opportunities. Or do some technical deep dives into the inner world of SVC or Storwize performance characteristics. Who ever is interested on meeting - just send me a note. Michael.Pirker@sva.de Until then Michael

The intention of VDisk copies is to protect servers against hardware failures. For this reason, it is important that the mirrors of the VDisk copies are stored on different storage systems. Here are some additional challenges in system administration and system monitoring. This document describes how to ensure that all volumes are stored on different sites. An wrong setup in this area can lead to an only 50% chance of surviving a fail over. If there is a mirrored pair on Site 1 and by an evil coincidence an another on Site 2 you have the... [More]

How analysis windows support storage performance analysis (and make it by factors faster) BVQ version 5 introduces a new interface which allows the grouping of logically connected views into dashboard-like analysis windows. These groupings can then be stored as favorites and can be used like recipes to help solve problems quickly. The following picture shows an analysis window which gives an overview of a complete storage system. This analysis window describes the data path and the load in the hardware in a way that allows for... [More]
